Freeze Frame Data

NOTE: 1st trip freeze-frame data values can only be displayed with Nissan's CONSULT, and are not displayed on GST scan tool.

PCM records engine operating condition when an emission related fault is detected. This single "snapshot" is stored in PCM memory to aid in diagnostics by indicating conditions present when DTC is detected. Freeze-frame data is kept in order of priority. If low priority freeze-frame data (priority 1) is stored and another freeze-frame fault should occur, with the same priority, only the original freeze-frame data will remain. Always record this information when reviewing information.

If MIL should illuminate, indicating a 2nd trip malfunction or a higher priority code, the lower priority freeze-frame data would be replaced with the priority 2 or 3 freeze-frame data. Should a priority 3 malfunction occur (misfire, A/T or air/fuel system fault), then any other lower priority freeze-frame data would be replaced with priority 3 freeze-frame data. See FREEZE FRAME PRIORITY IDENTIFICATION table. This recorded data is useful for determining conditions in which the malfunction occurs.

NOTE: Only one 1st trip DTC and one freeze-frame data "snapshot" can be stored in PCM. If using GST, 1st trip DTC freeze-frame information may not be accessible. Use CONSULT to retrieve 1st trip DTC freeze-frame information.
